This code is based on the work of Andre Zugman, specifically the 'subjmove.py' module (in the 'cli' folder) in his xnat-access repository.
The code has been reworked to allow much of the needed information (XNAT host URL, source and destination projects), and data to be found, to be input as CSV files. This module allows for the 'bulk' searching and moving of sessions of data between projects in XNAT (thanks to Catherine Walsh for tips on implementing this optimization!).
